Erik Buell Talks About AMSOIL Motorcycle Oils

Reduces Friction, Heat and Wear
In high heat conditions, AMSOIL Synthetic Metric Motorcycle Oil exceeds the standard for high-temperature film strength to deliver excellent wear protection. It keeps engines running cool by effectively reducing friction and heat, and it contains a heavy treatment of anti-wear additives to reduce wear regardless of operating conditions. AMSOIL Synthetic Metric Motorcycle Oil is thermally (heat) stable and contains maximum levels of oxidation-inhibitor additives. It is extremely resistant to volatility and is engineered to prevent damaging sludge and carbon deposits for superior engine cleanliness.

• Premium wear protection
• Smooth, confident shifts
• Cool, clean performance

Smooth, Confident Shifts
AMSOIL Synthetic Metric Motorcycle Oil contains no friction modifiers and promotes smooth shifting and positive clutch engagement. It is engineered to control heat and prevent slippage and glazing, promoting longer clutch life.

Controls Foam
High-rpm operation causes some motor oils to foam. When foam bubbles travel between gear teeth or engine components, they collapse, allowing metal surfaces to contact, causing wear. AMSOIL Synthetic Metric Motorcycle Oil contains advanced anti-foam additives that help prevent foam, allowing riders to confidently push their bikes to the limit.

high temperature viscosity test result

Provides Extreme Pressure Quality Protection for Gears
With AMSOIL Synthetic Motorcycle Oil, there is no need for separate transmission lubricants. It is absolutely shear stable and will not thin out from mechanical activity. AMSOIL MCF performs like a gear lube without the negative effects of extreme pressure additives. In the FZG gear test, AMSOIL MCF achieved a perfect score with a zero wear rating (see photo below).

Delivers Superior Rust Protection
Motorcycles are prone to rust from storage, humidity and short drives. Rust can cause major damage, such as uncontrolled wear, compression loss and blow-by. Good rust protection, however, comes by design and is not natural to motor oils. Unlike many motorcycle oils, AMSOIL Synthetic Metric Motorcycle Oil contains special anti-rust agents that deliver superior rust protection. With its high 11.1 total base number (TBN), AMSOIL Synthetic Metric Motorcycle Oil provides greater protection from acid corrosion and helps maintain internal engine cleanliness.

Provides Excellent Wet Clutch Performance
AMSOIL Synthetic 10W-40 Motorcycle Oil contains no friction modifiers and promotes smooth shifting and positive clutch engagement. AMSOIL MCF controls heat and prevents slippage and glazing, helping improve clutch life. AMSOIL Synthetic 10W-40 Motorcycle Oil meets the wet clutch frictional requirements of JASO Standard T903: 2006, MA/MA2 and ISO-L-EMA2 of ISO Standard 24254:2007.

MIXING AMSOIL
AMSOIL Synthetic 10W-40 Motorcycle Oil is compatible with conventional and synthetic motor oils;
however, mixing oils may shorten the oil life expectancy and reduce the performance benefits. AMSOIL does not support extended drain intervals where oils have been mixed.

Aftermarket oil additives are not recommended for use with AMSOIL motorcycle oil.

SERVICE LIFE
Recommended for use up to twice the motorcycle manufacturer-recommended change interval (miles/hours) or one year, whichever comes first, in engines and transmissions.

When using an oil filter other than AMSOIL Ea® Motorcycle Oil Filter, change the filter at standard intervals. Racing or modified engines are excluded from extended drain interval recommendations; oil changes are at the owner's discretion.

HEALTH & SAFETY
This product is not expected to cause health concerns when used for the intended application and according to the recommendations in the Material Safety Data Sheet (MSDS).

Been using this stuff 4 years exclusively since the price of Spectra went out of control. I have ridden and raced Yamaha's since 1964 and never had an oil leek with the exception of the oil seal on 650 twins clutch disengagement rod. This is a common problem with any oil, and it only ads 2 chain lubrication with an oily back rim. The problem I have been having is with the 650 Seca II clutch cover gasket they cant stop ANSOIL from seeping out after time.

Always Amazes Me...

From the first time I used Amsoil to present day use... I always am reminded about how good your products are. First time I used Amsoil in my 1996 Lincoln Mk VIII, it had a sticky valve and always made a tick tick tick noise...always. After two years of driving That Lincoln i tried Amsoil and 5 seconds after startup... that tick went away. Plus mileage went up a few points.

Fast forward to my first oil change on my 2013 Honda F6B motorcycle. Bought it used like most of my vehicles and I was getting around 34-36 mpg. I bought the Amsoil for Metric Bikes 10-40. First tank of gas I went up 4 mpg. I have been riding motorcycles for 40 years and I ride out in the Texas hill country pretty aggressively for fun. But how nice to get an average of an extra 20 miles of driving range from the same amount of fuel.

I use Amsoil in everything I own with an engine. It goes in my new car, my old bikes and my lawnmower. I use it when I service someone else's engine. I get extended oil changes in everything so it's less expensive than the bargain stuff from the local auto store. I use the Ea filters whenever possible because they filter smaller particles which means my engines last longer and run cooler. I can't think of any reason to use anything else.

I've been using Amsoil 10W-40 motorcycle oil in my street bikes for over 15 years. I had a CBR600 with 95000km that used Amsoil from the first oil change. That bike had a spirited life with lots of commuting and many high paced track days. At that high odometer it had great dyno numbers, didn't burn any oil, and had never had any engine problems. When I was replacing my clutch at about 85000km I inspected some engine internals and it was amazing how clean a free of wear everything was.

Longer Oil Change Intervals

I've been using this product in my GoldWing motorcycle shortly after purchasing it brand new in 2012. I noticed right away a smoother gear shift. I love the longer oil change intervals while still providing new oil protection.

Staying with Amsoil

I've been very pleased since switching to Amsoil back in 2010 and I'm still pleased with it. The company has an organized web site that is easy to navigate and there's plenty of product variety listed. Amsoil provides fast, efficient service, ie order processing and delivery. The prices are competitive and the 10x40 I buy for my Royal Star Tour Deluxe keeps everything running smoothly.

Great for my road bike. Great for my race bike.

I personally run AMSOIL 10W-40 Synthetic Metric Motorcycle Oil through my road bike for the street and race bike at the track. This oil has always held up very well for me and always seems to outlast the filter. I swap it out every time I make a filter change (just out of habit), but it always looks as clear as when I first put it in.

When racing, I'm always on the throttle and make very hard downshifts (probably worse than I should). I have yet to see this oil deteriorate on me, even when stressing a motor very hard. I couldn't be happier with its performance so far this race season.

I recommend AMSOIL products to everyone I come across, whether on the street or at the track. As long as they continue to make high quality products, I will continue to do so moving forward.

Great Product

I've used this product in my motorcycle for the past 3 motorcycles....It might be just me, but I find that the bike runs cooler, and quieter.....No difference in gas mileage, but overall, I'll be using this for as long as I own motorcycles.....contemplating using it in my car....why not.......adds to the resale value..........

Amsoil is the best.

Had another unknown oil in bike from person I bought bike from. I use Amsoil on my car so I bought it for my bike. I noticed immediately that bike was not as loud when driving it, but most importantly the shifts were smooth from the shift lever. Smooth shifts are nice, especially when you drive a lot. Try Amsoil, you won't be disappointed.

AMSOIL is AWESOME!

I use amsoil metric 1040 in my 2012 ZX14R. It takes a beating from the big 1441cc. Always shifts smoothly and always run smoothly. I also use AMSOIL for ATVs in my 2000 Warrior 350 sport quad. Again, takes the hard abuse and keeps the motor running cool and smooth. Solid clutches! Recently flushed the brake fluid in my ZX14R and replaced with AMSOIL DOT4 Brake Fluid. They just makebawesome quality products. I only trust my toys with AMSOIL!

Drag Racing using 10-40 Synthetic

I've been using Amsoil Synthetic 10-40 motorcycle oil for nine years in both my Kawasaki Z1000 and ZX14. Both bikes have way more than a thousand runs on each and never had an issue. I've won the Alaska Raceway open air championship four times in 9 years twice on each bike and believe in Amsoil products.

It's really good stuff.

If your on the fence about using synthetics in a wet clutch motorcycle, no need to worry. I purchased a new goldwing 1800 in 2001 and started running Amsoil at the first oil change. After putting 100,000+ miles on this bike, the clutch was just as sound as the day I rode off from the dealership. No slipping, chatter, sticking or any clutch related issues at all. I sold that bike a couple of years ago and it continues life today as a trike with the same clutch that came from the factory. Now belongs to a coworker and has a tad over 140,000 on it. I now have a 2014 gl1800 using Amsoil as well. I found it to help with less overall engine noise, paticurly the high pitch whine common to the 1800. Shifts were smoother and less clunky. Mileage may have improved a bit but hard to tell with the way I ride. I may be pushing 60 but I still have a very flexible right wrist. Didn't have to ponder about what oil to use. I'm sold on Amsoil and until something better comes along that's where I will be. No worries and no regrets.

Best motorcycle oil ever with a side effect of better gas mileage on my bikes than any other Goldwing using any other oil. Only problem last order I ordered 10W- 40 Synthetic and got 10W-30. But no problem used it anyway. Keep up the great work.

One tough oil

Let me first say that I have tried most of the other brands of synthetic motorcycle oils that come in various colors (red, green, purple) and none of them hold up like Amsoil. I commute daily on a Kawasaki ZX-14R, big motor, big power, tight package lots of heat. Everything else broke down within a few hundred miles ( the pretty colors of the oil soon turned into black goop) but Amsoil still look new after the first thousand miles !! Nothing but Amsoil goes in now.

Seems like a good product

I am a 1st-time amsoil buyer. I've been putting it in my 2014 ZX10R Ninja since I bought it in April of 2015. Coincidentally, it is the same weight recommended for a YZ250 2-stroke I bought this year (crank case). I am not a scientist and I don't have any rebuild stories to offer. When I bought my 2 motorcycles I wanted to take good care of them and the commo. department store oils just seemed inadequate. An Internet search revealed a strong following for amsoil so I gave it a try. Time will tell, but so far so good I guess.

Best oil money can buy

I have run this oil in 2 Yamaha sport bikes from the time I bought them new from the dealer (after initial break in) until their first valve adjustments at 40,000 kms. Let me start by saying not only have the bikes performed exceptionally with a lot of hot in town riding, but the engine internals look new as if they rolled off the assembly line with literally NO sludge. Even valve wear on both bikes. Switch over if you haven't done so already.

Switching from Motul 5100 Semi Synthetic

The Motul 5100 Semi Synthetic is a lot more viscous than the AMSOIL. In terms of performance, I have found any oil change be it a car, motorcycle, boat whatever etc always feels like it has a better “Get up and Go” after an oil change. The main reason I switched to the AMSOIL full synthetic is that full synthetic SHOULDN’T break down as quickly as a semi or conventional oil. THIS is where the extra $$$ for the AMSOIL should come into play. That being said it is hard to know when the breakdown period is with any oil, and the trick (in my eye) is to keep on top of regular oil changes in order to prevent breakdown from happening. After 3000kms the oil that I drained out of the CBR yesterday still looked not to bad and smelt okay. I think the bike runs a touch smoother with the AMSOIL because of the viscosity, it’s that much thinner of an oil, and the bike seems to idle lower and run more freely than with the Motul Semi Syn.

I have always heard good things about this product along with Mobil 1 Full Synthetic & Royal Purple…

The customer service and location of you guys makes this a smart choice!

Thanks for making the switch so easy, see you in another 3000kms.

I am very impressed from the first few kms to now. The response of the engine has greatly improved with this oil change. I don't think the bike has run this good in quite a while. I'll be definitely calling again to arrange more purchases of oil for this one.
